Population surveys are crucial for public policy planning and provide valuable representative data. In the health sector studies to identify and assess the prevalence of Arterial Hypertension (AH), a chronic non-communicable disease (NCD), along with its associated risk factors have been conducted.
This study aims to assess the effectiveness of a population health survey in estimating the prevalence of arterial hypertension (AH) in the Sorocaba municipality between August 2021 and June 2023.
The analyzed performance indicator is the precision (design effect - deff) of AH prevalence in adults (≥ 18 years) and their exposure to primary risk factors. The total sample included 1,080 individuals from the urban area, deemed sufficient to estimate a deff of 1.5. This cluster-based study utilized census sectors as clusters, with data collected through household interviews, standardized questionnaires, and measurements of blood pressure and biometric parameters. The deff calculation formula used was weighted variance / raw variance. The Research Ethics Committee approved this study, with registration CAAE 30538520-1-0000-5373.
The deff values ranged from 0.44 for chronic obstructive pulmonary disease to 1.63 for asthma, with a deff of 1.00 for AH prevalence.
The study demonstrated good precision in its results, with high receptivity and cooperation from participants. The cost-effectiveness of the research deemed appropriate. The technique of selecting households within clusters (census sectors) based on detailed mapping and demographic data from the Instituto Brasileiro de Geografia e Estatística (IBGE) proved to be practical and efficient, suitable for replication in other municipalities and for studying other NCDs.
人口调查对于公共政策规划至关重要，可提供有价值的代表性数据。在卫生部门的研究中，为了确定和评估动脉高血压（AH）的流行情况，这种慢性非传染性疾病（NCD）及其相关的危险因素已被研究。
本研究旨在评估 2021 年 8 月至 2023 年 6 月期间在索罗卡巴市进行的一项人口健康调查在估计成人（≥18 岁）动脉高血压（AH）患病率方面的效果。
分析的绩效指标是成人（≥18 岁）中 AH 患病率的精确性（设计效应-deff）及其主要风险因素的暴露情况。总样本包括城市地区的 1080 名个体，认为足以估计 deff 为 1.5。这项基于群组的研究使用普查区作为群组，通过家庭访谈、标准化问卷以及血压和生物参数测量收集数据。使用加权方差/原始方差的 deff 计算公式。研究伦理委员会批准了这项研究，注册号为 CAAE 30538520-1-0000-5373。
deff 值从慢性阻塞性肺病的 0.44 到哮喘的 1.63 不等，AH 患病率的 deff 为 1.00。
该研究结果表明精确度良好，参与者具有较高的接受度和合作性。研究的成本效益被认为是适当的。在基于详细的地图绘制和巴西地理与统计研究所（IBGE）的人口数据选择普查区内的家庭（群组）的技术被证明是实用和有效的，适合在其他城市复制，并适合研究其他非传染性疾病。
